Mountain loop trail around Cloud Peak, mostly within the designated Cloud Peak Wilderness area west of Buffalo, WY.  Elevation ranges from 8,300 feet to 10,925 feet, climbing over 4 passes.  Much of the route is above timberline for beautiful views, and passes by 4 lakes.  There are 4 main access trailheads, so hikers can connect from the east, north, west, or south - each adds a few miles of hiking before starting the loop.
